A tropical wave moved off the coast of Africa on August 6th. It
moved westward without any development,
crossing Central America and emerging into the Pacific ocean on the
16th. Thunderstorms began to organize
and by the 20th, it was an area of disturbed weather moving along the
Mexican coast. By the 22nd, once it
moved away from land, the system organized into a tropical depression
about 190 miles southeast of Baja
California. Moving northwest, the system strengthened into a
tropical storm early on the 23rd and a hurricane
early on the 24th. It reached category two intensity as it made
landfall late on the 24th. Slowly moving up the
spine of Baja California Sur, the system slowly weakened while dropping
significant rainfall. By the 26th it
had degenerated back into a tropical depression. By the 28th, it
became a vague area of cloudiness which moved
up towards Baja California Norte before dissipating. Below is its
track, provided by the National Hurricane Center.
